In China, Municipal Solid Waste (MSW) problems are growing fast. The annual waste generation increasing almost 10% per year and the population of municipalities is expanding, but sanitary landfill and recycling facilities are still rare to see. With rapid economic development, it is even harder to achieve waste reduction, reuse and recycling than developed countries which have significantly med...

The massive production of urban and agricultural wastes has promoted a clear need for alternative processes of disposal and waste management. The potential use of municipal solid wastes (MSW) as feedstock for the production of polyhydroxyalkanoates (PHA) by a process known as syngas fermentation is considered herein as an attractive bio-economic strategy to reduce these wastes. In this work, we...

The poor state of solid waste management in cities of developing countries is fast assuming the scale of a major social/environmental challenge. The main drivers of the waste problem in Nigeria, for instance, are poverty, high population and urbanization growth rates, compounded by a weak and underfunded infrastructure. The gravity of this problem is perhaps best reflected in the level of atten...

Sri Lanka is an island in the Indian Ocean with an area about 65 610 km(2). The population of the country is around 20.2 million. Hazardous disposal of municipal solid waste (MSW) is a major concern particularly in the most urbanized areas of Sri Lanka. However, the current waste management system does not facilitate any waste pre-treatment techniques before final disposal. As a consequence, th...

There has been a significant increase in municipal solid waste (MSW) generation in India during the last few decades and its management has become a major issue because the poor waste management practices affect the health and amenity of the cities. In the present study, various physico-chemical parameters of the MSW were analyzed to characterize the waste dumped at Gazipur landfill site in Del...

Egypt is well-known in the world not only for its old heritage but also for its valued presence in superior quality of textiles. However, the textile industry is both energy intensive and highly polluting. The production of textiles often requires high levels of water consumption and emits large quantities of pollutants to the environment. Therefore, it is very important to minimize its impact ...
